Analog Output Module Honeywell TK-HAO081

Product Description

The TK-HAO081 (Part Number: TK-HAO081) is a high-speed, high-density universal analog output module designed for Honeywell Experion PKS and Series A control platforms. It provides eight independently configurable output channels, each capable of delivering either voltage or current signals, offering maximum flexibility when interfacing with control valves, actuators, and variable frequency drives (VFDs).

Optimized for fast and precise control, the TK-HAO081 features 16-bit resolution and a sub-1 ms update time, making it well suited for high-performance control loops where tight response and signal accuracy are critical. Integrated 500 VDC galvanic isolation protects the controller backplane from field-side electrical noise and transient surges, ensuring reliable operation in harsh industrial environments.

Technical Specifications

Application Scenarios

• High-speed modulating valve control in pharmaceutical and fine chemical batching

• Providing speed or torque references to VFDs in pumping and compression systems

• Multi-channel analog control for boiler and turbine auxiliary systems

• Interfacing with legacy analog instruments in environmental and emissions monitoring

Frequently Asked Questions

Can voltage and current outputs be mixed on the same module?
Yes. Each of the eight channels can be independently configured for either voltage or current output, provided total loading remains within the module’s specified limits.

Does the TK-HAO081 require an external power supply for current loops?
The module receives logic power from the Series A backplane. For 4–20 mA outputs, loop power is typically supplied by an external 24 VDC field source, commonly via the termination assembly.
